MSPM0L1106: Disabling BSL Error

Hi Ambroise,

BSL is enabled/disabled using Sysconfig.

Hi Dennis,

Yes, that is what we have been doing.

Whenever we disable the BSL in the syscfg, we cannot configure I2C SCL Pin as PA1/NRST and the compiler throws the error shown before. Is there a proper way to disable BSL while setting I2CC as PA1/NRST

BBest regards,

I see you are using I2C?  By chance, do you have it's pinmux configuration setup to use PA1 as the SCL?

Other things to try in the BSL pin configuration is select the ALT pins (PA11).  (this might be an issue is using PA11 for other purpose, but let's see what is causing the conflict).

Hi Dennis,

Yes, we are using the PA1 for SCL. P11 is used as GPIO. We are hoping to not change the pin assignments to prevent a layout change.

P8, P9, P10 are available though.

Best regards,

Ambroise

HI Ambroise,

Have the customer delete the I2C configuration in sysconfig.  Then go into NONMAIN and deselect the BSL.  Last, create a new I2C configuration in sysconfig.  I think this happend to another customer a while ago and there was something with the order in which the configurations are created in sysconfig.

Let me know if this works.

Hello Dennis,

We tried your recommended steps, unfortunately the same error occurred. The moment the "Enable BSL" is disabled, the I2C SCL Pin under "BSL I2C Pin Configuration" gets reset and throws an error.

Any thoughts on this?

Thank you and best regards,
Ambroise

Hi Ambroise,

See if you can get the customers *.syscfg file and let me take a look at it.

Hello,

Yes the customer updated to SDK 1.2.0.05 and Syscfg 1.18.0.
I tested it and I also got some errors:

Disabling "Configure Unused Pins" does resolve this issue, but then BSL cannot be deactivated while defining the I2C SCL pin as PA1/NRST. So the original issue remains.

Hello Dennis,

Thank you for looking into this, we have built an entirely new sysconfig file from scratch with the new SDK.  We have never managed to deactivate the BSL with whatever trick. It will still not boot even with a new sysconfig file.

 Also, the current error shown with the “IOMUX_PINCMNone” issue is only due to the “set unassigned pin” setting. 

Best regards,

Ambroise

Hello Dennis,

We were not able to properly resolve these issues so far. Have you heard back from the SW team?
Thank you and best regards,

Ambroise
